Whooping cough vaccine can make a difference

Since October last year all pregnant women have been offered the whooping cough vaccination to protect their newborn babies until they can be vaccinated starting at two months of age. The vaccination of pregnant women helps to boost the short-term immunity passed on by women to their babies while they are still in the womb.

In the first 18 weeks of 2013 there were 42 confirmed cases of pertussis; out of these only two were in babies under three months. For the same period last year, there were 51 cases confirmed, out of which 28 were reported in babies under three months. Although there has been a slight reduction in the number overall, there has been a dramatic reduction in the under three month olds. This would suggest that the vaccine can make a difference to this age group and protect those who need it most.

Dr Richard Smithson, Consultant in Health Protection, PHA, said: “So far there has been a good response from pregnant women to getting vaccinated, but we would urge those women who are over 28 weeks pregnant and haven’t yet had the vaccine to get it as soon as possible as whooping cough is still about.

“We are very pleased with the early results of this programme and the big reduction we have seen in the number of cases in young babies – the group who are most vulnerable and whom we most wanted to protect.

“Whooping cough is a disease that can cause long bouts of coughing and choking, which can make it hard to breathe. It can be very serious for young children, and even fatal for babies under one year old.

“Newborn babies are likely to have little or no protection against whooping cough until they have been fully vaccinated themselves. The vaccination of pregnant mothers will help to protect children from birth until they are old enough to be vaccinated themselves, as antibodies passed from the pregnant mother to her unborn child help protect the baby in the first few weeks of life. Vaccination of babies is routinely given at two, three and four months of age, with a booster administered three years later.

“The vaccine which is being given to expectant mothers through this programme, called Repevax®, has been used with young children for many years now and has an excellent safety record. There is no evidence to suggest that the use of this vaccine during pregnancy is unsafe for either the expectant mother or their unborn baby. The vaccine is not live and cannot cause whooping cough. There may be some mild side effects from this vaccination, such as swelling, redness or tenderness, although serious side effects are extremely rare.

“The best time to get the vaccine is between 28 and 32 weeks of pregnancy, but if a woman misses out during this time she can still get it after 32 weeks. The vaccination programme will be coordinated through GPs who will contact eligible women.”

All parents should ensure their children are vaccinated against whooping cough on time, even babies of women who’ve had the vaccine in pregnancy. This is to continue their baby’s protection through childhood. Parents should also be alert to the signs and symptoms of whooping cough which include severe coughing fits accompanied by the characteristic ‘whoop’ sound in young children, and by a prolonged cough in older children or adults. It is also advisable to keep babies away from anyone showing the signs and symptoms of whooping cough.
